Seiko SPB263

Built for the Ice Diver - U.S. Special Edition. Designed for those who treat life as the ultimate adventure, the Seiko Prospex line meets every challenge with technological excellence and style. Following last year's designs paying tribute to the durability of Seiko watches in the coldest and iciest conditions, this new U.S. Special Edition was inspired by the landmark 1970 diver's watch, a favorite of daring adventurer Naomi Uemura, the first man to conquer the highest mountains on five continents. Including the original's signature built-in crown protector at 4 o'clock, this exceptional watch features a distinctively patterned dial representing the tracks Uemura forged in deep snow, in a gradated blue evoking one of the many changing tones of light reflecting off glacial ice formations. Following ISO standards for scuba diving to depths of up to 200 meters, this exceptionally durable timepiece is crafted of stainless steel with super-hard coating, and features a screwdown Special Edition caseback, scratch-resistant anti-reflective sapphire crystal, screwdown crown and tri-fold push-button release clasp with secure lock and extender. Framed by a gray uni-directional rotating elapsed timing bezel, the dial includes a date calendar, as well as LumiBrite hands and markers for enhanced visibility. The 24-jewel automatic movement beats at a frequency of 21,600 vibrations per hour, with a power reserve of approximately 70 hours, and offers manual winding capability. 200m Water Resistant
